That almost looks like a Photoshop, but then I saw the reflection of the arena roof in the Marriott glass.

I'm still bummed that the skylights were deleted from Pelli's design for the roof, but at least this is cool! Hopefully it doesn't fade too quickly.

This roof is tailor made for blimp or helicopter shots during sports coverage. I guess some people might see it from planes approaching ORD or MDW, but those are usually pretty high up when passing over downtown.
